To all whom it may concern:

Be it known that I, O'rro Cassm.,subject of the Em eror of Germany,residing at Vienna, in t e Empire of Austria-Hungary, haveinvented-certain new and useful Imrovements in the Process forManufacturmg Crude-Oil Soap, of which the following is a. specification,reference being had therein to the accompanying drawing.

The present invention relates to a process for the manufacture of crudeoil soap.

It is well known that certain quantities of crude oil or thedistillations obtained therefrom can be incor orated in common soaps,but the addition 0? considerable percentages of such oils has nothowever as yet been achieved.

According to the resent invention it has been discovered-that theaddition of montanic acid the materials employed in the usual methods ofmanufacturing soa s have the ropert im arted thereto, of bemg able to asorb ex ingly lar e percentages, u to 200% by weight of refined orunnefine crude oil or its distillates.

As a formula for execution I give the following example: 20 parts ofcaustic soda are dissolved in 100 parts of water and intothe obtainedsolution are stirred, while warm, 20 parts of rosin and 10 parts ofmontan wax. When the montan wax has been completely 100 parts (or apercenta up to 2003b '0 the soap base) of refinetf or crude o' are addedunder constant stirring and the concoction is brought to boiling again.

The material known in trade by the name of montan wax contains largequantities of montanic acid and is consequently well adapted to thepresent urpose and the same will ensue i instead of montanic acids thesame quantity of montan wax be added. I have also found that theby-products obtained in the manufacture of montan wax or montanic acids(see Geratent trian atent 1456) in consequence of the montanic acidwhich they contain, will reset on the component substances in soupmanufacture in such a manner that the sai by-products may be used incarrying divided condition, consgguently wi dissolved through boilmg'spleeification 101378 and Ansout the invention. The action of thebyproducts though naturally not so efiective v as that of montan wax ormontanic acids,

being nevertheless suflicient for technical pur osw.

T e process is carried out in the following manner: Toone of .thecomponents or to the total mass, of soaps manufactured according toknown processes montanic acid is added, thus enabling up to 200% ofcrude It is, however, evident that the quantity of montan wax added mustbe eater than if pure montanic acid were emp oyed and likewise theamount of by-products added must be eater than if montan wax were added.

oaps prepared according to this process hold the crude 'oil in anextremel well and may be dilu with almost any amount of water. Soap ofthis kind has considerable cleansing power and may therefore be employedfor removing varnishes and paints. Owing to the above mentioned to rtyof being able to stand almost unlimited dilution with water the soap isextremely suitable for street sprinkling purmanufacture of crude oilsoap, which consists in adding montan wax to thesoap substance beforecombinin with crude oil.

2. The herein descn process for the manufacture of crude oil soap, whichconfinely 1 lather sists in 'addin by-products containing montan wax tot e soap substance before combining with crude oil.

In testimony whereof I hereunto aflix m signature in presenceof twowitnesses.
